Sponge for HP41c standard case

The HP 41 cases are tall to fit the card reader (I think) and so if you don't have one installed, the case is an annoyingly poor fit for an HP 41. I always worry the calculator will get scratched from sliding around in the case. And the case can flex from not being supported.

These little sponges are worth their weight in gold. The calculators get a firm fit in the case and everything finally feels like it should.

Great idea, thank you!

Same as the original in size and texture. Arrived in only one week in Canada.

It is made with excellent quality and craftsmanship. I was very pleased when I received it.
Many thanks!
